By the same token it would be wise to refrain from turning on any optimization that breaks programs which depend on wrapping signed integers. Silently breaking LIA-1 semantics is imprudent.
I am not so sure about that conclusion, which I why I would like to see more data. It maybe that the loop induction optimization *is* significant, and you must admit it is really really hard to imagine real world code that depends on wrapping in this context.
